A PCBA board used for intelligent vehicle lamp control comprises an MCU1, an LED control system, a power supply control system, a VBAT and a vehicle machine system, the MCU is controlled by the vehicle machine system, the LED control system comprises a plurality of groups of LED driving modules, LEDs and an LED lightening detection module, and the power supply control system comprises a power supply manager, a voltage detection module, a current detection module and a bus switch. After the structure is adopted, the automobile lamp control system has the following advantages that through the MCU, the linear driving IC, the DC-DC, the signal transceiver, the MOSFET and the like, automobile lamp intelligentization, self-adaption to a high beam and adjustment of a lamplight irradiation area are achieved, dazzling to drivers of other automobiles is avoided, and driving safety is guaranteed; the LED driving modules are coordinated through the single chip microcomputer to achieve the light effect, each part of LEDs do not need to be driven, meanwhile, through MCU algorithm control, various pixel quantities can be achieved through fewer lamp beads, and the problems of heat dissipation and the like caused by dense lamp beads are solved.

    一种用于智能化车灯控制的PCBA板,它包括MCU1、LED控制系统、电源控制系统、VBAT和车机系统,MCU由车机系统控制,LED控制系统包括多组LED驱动模块、LED、LED点亮侦测模块,电源控制系统包括电源管理器、电压侦测模块、电流侦测模块和总线开关。采用以上结构后,本发明具有如下优点:本技术通过包括MCU、线性驱动IC、DC‑DC、信号收发器、MOSFET等等,来实现车灯智能化,实现自适应远光灯,调整灯光照射的区域,避免对其他车辆驾驶员造成炫目,保障行车安全;通过单片机来协调各个LED驱动模块去实现灯光效果,而不用去驱动每一部分LED,同时通过MCU算法控制,可以利用更少的灯珠数量来实现多种像素量,解决密集灯珠造成的散热等问题。
